Specification of Letters Patent.

Patented Aug. 2?, 1912.

Application filed October 31, 1911. Serial No. 657,717.

To all whom it may concern:

Be it known that I, GEORGE A. BELDING, a citizen of the United States, residing at Mis soula, in the county of Missoula and State of Montana, have invented new and useful Improvements in Culverts, of which the following is a specification.

This invention relates to culverts.

The object of the invention is to provide a sectional culvert in which the joined parts are so constructed that the sections of the culvert will properly nest together for transportation and occupy the minimum amount of space.

A further object of the invention is to provide. a sectional culvert having interlocking joints in which the sections are adapted to nest together for transportation and then set up at the point of use.

Further objects ofthis invention will appear as the following specific description is read in connection with the accompanying drawing,-which forms a part of thisapplication, and in which Figure 1 is a side elevation with parts set up. Fig. 2 is a section on the line 22 of Fig. 1. Fig. 3 is an end elevation showing the upper and lower sections nested together.

Referring more particularly to the drawing, 1 represents the lower section and 2 the upper section of a metallic culvert. The lower section is substantially semi-circular in cross section and has its upper edges bent outwardly to form seats 3 and then upwardly to form retaining flanges 4. The upper section is also substantially semi-circular in cross section with its upper edges bent inwardly to form abutments 5 and retaining flanges'fl. The sections may be either plain or corrugated and in the latter instance, suitable connecting bolts 7 pass through joints of every other corrugation, as shown, so as to firmly hold the upper and lower sections together. In practice, a plurality of upper sections are connected together by lapping their ends, as shown at 8, and the lower sections are connected in a similar manner, the joints 8 of the upper and lower sections being arran ed in staggered relation, as shown, that is, the joint between the sections of the upper portion of the culvert cross in the middle of the lower section. When the upper and lower sections are connected together, the flange 6 extends down into the section 1, while the flange 4 encompasses a portion of the upper section 2. Thus, the upper section 2 is prevented from spreading and the lower section 1 prevented from collapsing. When the upper sections are nested within the lower sections, they are simply inverted so that the seats 3 will rest upon the retaining flanges 6 of the lower sections.

What is claimed is 1. A culvert comprising upper and lower sections, outwardly and upwardly extending flanges on the lower sections, and inwardly and downwardly extending flanges on the upper section adapted to interlock with the flanges of the lower section.

2. A culvert comprising upper and lower sections, outwardly and upwardly extending flanges on the lower sect-ions, inwardly and and downwardly extending flanges on the upper section adapted to interlock with the flanges of the lower section, and bolts passing through said flanges for securing the sections together.

3. A culvert comprising upper and lower metallic sections substantially semi-circular in cross section, outwardly and upwardly extending flanges on the lower section, inwardly and downwardly extending flanges on the upper section, said sections and flanges being corrugated, and bolts passing through alternate corrugations of the flanges and securing the sections together.

4. A culvert comprising upper and lower sections, right angular flanges extending outwardly from one of the sections, oppositely disposed right angular flanges extending inwardly from the other section and adapted to interlock with the flanges of the first named sections, and bolts passing through said flanges for securing the sections together.

In testimony whereof I aflix my signature in presence of two witnesses.

- GEORGE ABELDING. Witnesses:
